50 partly in section and partly in elevation, of 514,098, filed August23, 1909 of which this an engine cylinder having my valve mech--application is a division. 7

anism applied thereto, part of the crank case being shown; Fig. 2represents a transverse sectional view corresponding to the At one'sideof and preferably cast integral with each cylinder, are two cylindricalvalve casings or chamber 16. The water jacket, to which reference hasbeen made hereinbefore, is extended around the upper portions of thevalve casings, as shown at 17, and the inlet duct for the coollng liquldcommunicates with this portlon of the jacket, as indicated at 18. Asillustrated herein, the axes of the valve casin s are substantiallyparallel with the axes 0 their correspondingly cylinders. Each cylinderis provided with an expanding or fan shaped duct 19 projecting therefromand preferably cast with and forming part of the casings 16 of an inletand an exhaust valve. The outerwall of the duct is projected outwardlyaround the outer sides of the valve sleeves, whereby a port 20 isprovidedentirely around each valve sleeve, enabling the pressure in thecylinder and in the duct 19 to be equalized around such sleeves. Theport 20 of each of they valves forms in effect part of the duct 19.

Slidably mounted within each valve casing 16 is a sliding valve sleeve21. This sleeve is provided, intermediate of its ends, with a segmentalseries of ports 22 which are adapted to register with the ports 20 whenthe sleeve is in an intermediate position, as will appear moreparticularly from Fig. 1. The lower end of each sleeve is operated by aconnecting rod 23, the lower end whereof is mounted upon a wrist pin 24projecting from the cranked lay shaft 25. This shaft is shown as mountedwithin 1 a casing 26' which receives the lower ends of the valve casings16 and is in open communication with the same. This casing is adapted tocontain oil whereby the valve parts thereabove may be lubricated by thesplash system and .is shown as provided with a removable cover 27. Aswill appear from this figure, the crank shaft 25 is offset axially fromthe valve casings 16, whereby adjustment for timing may be convenientlyobtained.

Suspended within each valve casing and forming therewith an annularguide for the sliding valve sleeve 21, is the inner sleeve or bushing28. These inner sleeves or bushings are shown as suspended from the topsof their respective valve casings, each sleeve or bushing being providedwith a flange 29 whereby it is mounted upon the top of its respectivevalve casing. At its upper end, each of the sleeves or bushings iscontracted in diameter, as shown at 28 to provide with the upper end ofthe outer valve casing an oil chamber 29 with which the oil duct 30communicates. The sleeve or bushing 28 is provided with a segmentalseries of ports 31 which register with the port 20 in the correspondingvalve casing as well as with the ports 22 in the sliding sleeve valve asthe latter is reciprocated within the annular seat formed between thesleeves 16 and 28. Be low the ports 31, and preferably immediately belowthe same, the sleeve or bushing 28 is provided with a partition 32forming an abutment, which extends across the bore of the said sleeve orbushing and isolates the upper portion thereof from the lower por-- tionof the valvecasing 16 and from the easing 26 containing the lubricatingoil. To further isolate the fluids within the interior of the innersleeve or liner 28 from the oil chamber and to prevent the said fluidsfrom coming in contact with such oil, packing rings 33 are provided inthe outer surface of this liner or bushing above and below the ports 31and below the abutment 32.

, provided with a spiral gear 37 meshing with a similar gear 38 on thelay shaft25. These gears are made of such size that the inlet andexhaustvalves 21 make one complete stroke for every four completestrokes of the piston 4;.

In operation the engine described herein operates in the same manner asthe ordinary four-cycle engine, the exhaust valve being closed when theinlet valve is open. After the admission takes place, a compressionfollows, and the-inlet valve is then closed, the exhaust valve beingplaced so as to be closed at this time also. The explosion next follows,with both inlet and exhaust valves closed and, at the end of theexplosion stroke of the piston 4, the inlet valve will have reached theuppermost limit of its stroke.

The exhaust now takes place, with the'inlet valve closed and the exhaustvalve open and, following this, admission takes place with the inletvalve open and the exhaust valve closed, as will be understood by'thoseskilled in this art. From the construction and arrangement of parts, itwill be evident that the inlet and exhaust valves are open when thesevalves are each in an intermediate position and that the ports thereofare opened and closed by a continuous movement of their respectivevalves in the same direction, such opening and closing occurring duringa single cycle of the four-stroke engine, the valve movements insucceeding cycles being in opposite directions; also that the ports ineach tubular valve or valve sle V are caused to register with the portsi. the valve casing only during alternate reciprocations of the piston.

It will be observed that, by the arrangement of the outer valve casingsand the inner liners or bushings, a flue or chimney is 1,238,308 y a i iprovidedin each exhaust valve for the exhaust gases, which flue orchimney extends above and away from the ports in the liner or bushingand that extended insulating films of oil are provided. and maintainedabove and below the ports in the liner and in the surrounding valvecasing. It will be evident that, by reason of this construction andarrangement of parts, the temperature within the liner will bemaintained substantially constant whereby, in the case of an exhaustvalve, like constant temperature and constant pressure may be maintainedin the exhaust gases with corresponding uniformity in operation,particularly in the scavenging of the combustion s ace of the engine.Furthermore, the coo ing liquid in a jacket surrounding the cylinders islargely protected against the heating action of these gases. In the caseof an inlet valve, the entering combustible fluids are subjected to asubstantially constant temperature enabling a fixed density to bemaintained therewithin.
